Free Online Video Editor with AI Captions

ToolDeck Video Editor is a free browser-based editor that adds no watermark, needs no account and never uploads your files. It includes a multi-track timeline, free AI captions, silence removal and MP4 export up to 4K. It is a strong fit for short videos, social clips and private footage. If you need stock footage, cloud templates or motion tracking, a cloud editor suits you better.

Yes. ToolDeck sets no credits, no daily cap, no video length limit and no sign-up. The practical limits come from your device: browser memory, processor speed and graphics card, plus a 1 GB limit per imported file.

No. Open the page, drop in your files and start editing. There is no login, no email wall and no trial period.

It covers the same core job: multi-track editing, text, filters, transitions and automatic captions with no watermark. Several reviews report that CapCut moved auto captions and some AI tools behind a paid plan, so check its current free tier. ToolDeck does not include cloud features such as stock templates, stock music, motion tracking or AI background removal, and its AI captions currently recognise English speech.

Many online editors upload your files and render in the cloud, and some add watermarks or limits on free plans. ToolDeck edits and renders inside your browser, so files stay on your device and exports have no watermark. Cloud editors offer stock libraries and cloud AI that ToolDeck does not.

No. Editing and rendering happen inside your browser tab. To check, open the Network tab in your browser developer tools while you edit and export. The only downloads are the editor code and, if you use AI captions, the open speech model from a public CDN.

Your files are processed locally and never sent to ToolDeck servers, which makes it a good fit for private or client footage. Keep your browser and device updated, and avoid shared computers for sensitive work.

No. Whisper speech recognition runs on your device. Only the open model file is downloaded once from a public CDN and then cached in your browser. Your audio is not sent anywhere.

After the page and editor code have loaded, editing and rendering run locally and do not need the internet. AI captions need a one-time model download first. Reloading the page while offline may not work unless your browser has cached it.

Import your video, open the AI Captions and Subtitles tab on the left and press Generate Captions. Whisper runs on your device and adds caption clips on the Text track. You can edit, restyle or delete each one. Captions are not perfect, so review the text before exporting.

The built-in speech model is English only, so AI captions work best for clear English audio. Accuracy drops with background noise, strong accents and music. For other languages, import an SRT or VTT subtitle file and burn it into the video.

Yes. Open the AI Captions and Subtitles tab, press Import SRT / VTT file and choose your file. The cues become editable caption clips that use your chosen style, and they are rendered into the exported MP4. ASS and SSA files are not supported.

Yes. After generating, importing or adding captions, open Export and press SRT or VTT. Only captions are exported; ordinary text titles and stickers are not.

Accuracy is good for clear English speech and drops with background noise, strong accents and music. Always review the text, especially names and technical terms. Captions are normal text clips, so fixes are quick.

Yes. Select a clip, open the AI tab, set the silence level and minimum pause, then press Cut silent parts. It splits the clip at the quiet parts and removes them. Tick Apply to all clips to process every clip on that track.

Scene detection finds cuts in a clip and splits it at those points. Beat detection finds the rhythm of your music and adds markers so clips and cuts can snap to the beat. Both run locally in your browser.

Yes. Choose 9:16 in the Ratio menu. The editor sets the ratio automatically when your first clip is vertical. Turn on Blurred background to fill the sides when a clip does not fit.

Yes. Open the Style tab on an overlay clip, enable chroma key, pick the key colour and adjust tolerance. Place the clip above your background clip.

Yes. In the Audio tab, press Record. Playback starts so you can talk over the video, and the take is added to the Audio track. Your browser asks for microphone permission first.

Yes. Set clip speed from 0.25x to 4x. You can also freeze a frame, detach audio from a clip and fade volume in or out.

The timeline has a main track, an overlay track, a text track and two audio tracks. The number of clips is limited only by your device memory.

Yes. Drop several clips on the timeline to merge them, drag clip edges to trim, and press S to split at the playhead. Ripple delete and Close Gaps remove empty space on the timeline.

Yes. Space plays and pauses, S splits, Delete removes a clip, Shift+Delete ripple deletes, Ctrl+D duplicates, Ctrl+Z and Ctrl+Y undo and redo, arrow keys step frames, and plus and minus zoom the timeline.

Import MP4, WebM, MOV, MKV (if your browser can play it), common image formats and MP3, WAV, M4A and OGG audio. Export is MP4 (H.264 with AAC audio) in Chrome and Edge. The recorder engine exports MP4 or WebM depending on the browser. Captions export as SRT or VTT, and the audio mix exports as WAV.

You can export up to 4K at 60 fps if your device has enough memory and processing power. For most social videos, 1080p at 30 fps is faster and plenty sharp.

Export uses WebCodecs to encode H.264 video. With hardware acceleration on, your graphics card encodes the video when the browser supports it. With it off, the CPU does the work. If your browser has no WebCodecs, a real-time recorder is used instead.

Without a graphics card, rendering runs on the CPU, and 4K, 60 fps or many layers make it slower. Try 1080p, 30 fps, fewer effects and close other tabs. Mobile devices are much slower than a desktop.

Each imported file can be up to 1 GB. Projects of a few minutes work best. Very long projects can run out of browser memory, so split them into parts.

Usually the browser ran out of memory. Close other tabs, lower the resolution or frame rate, remove heavy effects, trim big source files first, or split a long project into parts. Chrome or Edge on desktop is the most reliable.

Chrome and Edge on desktop give the best results because they support WebCodecs for fast GPU or CPU export. Firefox works with the compatibility engine. Safari has limited support for some canvas filters.

The editor loads on mobile, but the layout and performance are built for desktop. For serious editing and exports use Chrome or Edge on a computer.

Yes. It runs in a modern browser on any operating system. Use the latest Chrome or Edge for the best speed.

Only use music, footage and images you own or are licensed to use. Ignoring copyright can get videos blocked or taken down on social platforms. This is general information, not legal advice.

ToolDeck adds no watermark and claims no rights over your exports. Whether you can use a video commercially depends on the rights to the footage, music, fonts and images inside it, so make sure you are licensed to use them.
